Product Description Seachem PhosGuard 1L Directions Can generate heat when first contact with water. Pre-moisten by adding a double volume of fresh water followed by a rinse. For best results, PhosGuard should be rinsed before use and placed so that water flow through it is maximized, but not so that it falls against itself in flow. It can be used in a canister filter, media chamber, box filter or any high flow area of a trickle filter. The use of a filter bag is recommended. Use 3 oz (1/3 cups) for any 200L salt water or 400L of fresh water. Box Contains water treatment
